Version: 0.1.7 (using KDE KDE 3.5.6) Installed from: Ubuntu Packages OS: Linux The Hardware tab of displayconfig is showing Driver as nv when, in fact, I'm using the nvidia driver. chris@HAL421:~$ modprobe -l nv* /lib/modules/2.6.20-13-generic/kernel/drivers/video/nvidia/nvidiafb.ko /lib/modules/2.6.20-13-generic/kernel/drivers/char/nvram.ko /lib/modules/2.6.20-13-generic/kernel/drivers/char/agp/nvidia-agp.ko /lib/modules/2.6.20-13-generic/volatile/nvidia.ko /lib/modules/2.6.20-13-generic/volatile/nvidia_legacy.ko chris@HAL421:~$ relevant section of xorg.conf: Section "Device" Identifier "NVIDIA GeForce 7300LE" Driver "nvidia" BusID "PCI:1:0:0" Option "UseFBDev" "true" Option "AddARGBVisuals" "True" Option "NoLogo" "True" Option "XAANoOffscreenPixmaps" "true" EndSection Also, the Size, Orientation & Postitioning tab shows the correct resolution but the refresh rate is incorrect. My refresh is 60Hz, the applet shows 50Hz - with the only 2 other options being 53Hz & 54Hz. NOTE: I am using the proprietary NVIDIA driver, not the free nv driver. System: Intel(R) Celeron(R) D CPU 3.20GHz NVIDIA GeForce 7300LE 128MB HP vs15c LCD Monitor
This was resolved by adding: Option "DynamicTwinView" "False" to the Device section of /etc/X11/xorg.conf, as detailed in: http://us.download.nvidia.com/XFree86/Linux-x86/169.04/README/chapter-07.html [QUOTE] Why is the refresh rate not reported correctly by utilities that use the XRandR X extension (e.g., the GNOME "Screen Resolution Preferences" panel, `xrandr -q`, etc)? The XRandR X extension is not presently aware of multiple display devices on a single X screen; it only sees the MetaMode bounding box, which may contain one or more actual modes. This means that if multiple MetaModes have the same bounding box, XRandR will not be able to distinguish between them. In order to support DynamicTwinView, the NVIDIA X driver must make each MetaMode appear to be unique to XRandR. Presently, the NVIDIA X driver accomplishes this by using the refresh rate as a unique identifier. You can use `nvidia-settings -q RefreshRate` to query the actual refresh rate on each display device. This behavior can be disabled by setting the X configuration option "DynamicTwinView" to FALSE.
